Update module support level on a variety of modules and compiler options

Some core support modules and compiler options were no longer tagged with a
module support level.  This patch adds 'core' back to those options.

Note that this patch modifies a few of the patches provided by Andrew Latham
slightly.  res_curl and res_fax are both 'core' supported modules.
